BOBBlN-WINDER.

SPECIFICATION forming part of Letters Patent No. 260,734, dated July 11,1882.

Application filed February 6, 1882. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. BAKER, of Cleveland, in the county ofOuyahoga and State of Ohio, have invented certain new and usefulImprovements in Bobbin-Winders; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and usethe same.

Myinvention relates to bobbin-winders; and it consists in the peculiarconstruction of the same, as will be hereinafter fully set forth andclaimed. I

In the drawings, Figure l is a view of my bobbin-winder, showing itattached to the standard ofa sewing-machine. Fig. 2is a side elevationof the same, with the presser-pad in the position it occupies while inoperation. Fig. 3 is a side elevation, showing the presserpad thrownback from the bobbin. Fig. 4 is a view in section of the revolvingspindle, showing the manner of securing the bobbin in place andpreventing it from slipping. Figs. 5 and 6 are views showing anothermanner of constructing the presser-pad.

A is a bracket. Bis a spindlejonrnaled in said bracket, which isprovided at one end with a friction-wheel, O, and at its inner end it isrecessed or made concave and provided with a pin, a, which is adapted toengage with a hole in the end of the bobbin, as shown in Fig. 4. D isanother spindle, also journaled in the bracket A, which is provided witha spring, and acts to hold the bobbin E tightly in the recess in the endof the spindle B.

F are arms extending upward from the bracket A; but there may be onlyone arm, as shown in Figs. 5 and 6. Below the upper end or ends of thearm or arms F is secured a a grooved roller, 1).

curved bar, F, which Ipreferably provide with This curved bar F is soformed as to be equidistant at every pointfroni an eye, G, and the endsof the arms F serve as guides or guards for the thread and prevent itsslipping off the ends of the bar F.

H is aspring-pressure pad, which may be formed as shown in Figs. 2 and3viz., with a roller at its upper end-or it may be made as shown in Fig.5viz., with a smooth flat face.

M scribing witnesses.

The function of this pad is to press against the thread while the bobbinis being wound and act to distribute the thread evenly on the saidbobbin.

It will be seen that my curved bar is separated some distance from thebobbin, and that 5 5 the convex edge or surface of this baris oppositefrom the axis of the bobbin, and not set off to one side, as shown inpatents to Wm. Harrison Newton, dated May 14, 1872, No.126,829, andKennedy and Linny, dated March 14,1876, No. 174,630. Thus constructed, Itind that the thread is less liable to overlap and the bobbin is moresmooth and evenly wound.

The operation of my device is as follows: The thread is passed throughthe eye G, and 6 from thence is passed over the roller 1) on the bar F,or it may be passed over the bar itself. The end of the thread is thensecured to the bobbin and the bobbin set in motion, and afterit has beenwound around the bobbin a few times (enough to hold it and prevent itfrom slipping) the presser-pad is caused to press against the bobbin.With the curved bar placed as de cribed, and the fixed point or eye G,and also presser-pad H, I find that there will be no liability of thethread being un-, evenly wound.

. What I claim is- 1. In a'bobbin-winder, the combination, with r apresser-pad adapted to press against the bob- 8o bin, of a bracketprovided with upwardly-projecting arms, and a curved threaddistributingbar secured to said arms below the upper ends of the latter,substantially as set forth.

2. Ina bobbin-winder,the combinati0n,with apresser-pad adapted to pressagainst the bobbin, ot' a bracket provided with upwardly-projectingarms, and a curved thread-distributing bar secured to said arms andprevided with end guards for the thread, and with a roller,substantially as set forth.

In-testimony whereof I have signed my name to this specification in thepresence of two sub- GEORGE W. BAKER. Witnesses:
